Prototype X: A Cost-Based Design Optimization of an Upper Stage Liquid Propulsion Module with Green-Storable Propellants

This paper investigates the cost­-benefit, payload performance and technical feasibility of green storable upper stage design concepts on their potential implementation with existing launchers. Since the demand for reliable, safe, and cost­-effective transport to space is growing, it is necessary to find sustain­able rocket propellant solutions....

Electrothermal microthruster

Electrothermal propulsion can be seen as an intermediate concept between electrical and chemical propulsion. Propellant heating typically happens by means of a resistance (resistojet) or an electrical discharge (arcjet). For the extremely miniaturized applications that will be discussed in this chapter, resistojets are by far the most...

Review of state-of-the-art green monopropellants: For propulsion systems analysts and designers

Current research trends have advanced the use of “green propellants” on a wide scale for spacecraft in various space missions; mainly for environmental sustainability and safety concerns. Small satellites, particularly micro and nanosatellites, evolved from passive planetary-orbiting to being able to perform active orbital operations that may...

Modular impulsive green-monopropellant propulsion system for micro/nano satellites high-thrust orbital maneuvers (MIMPS-G)

Innovation in small-satellite modern space missions and applications require propulsion capabilities to enable active operations in orbit, such as formation flying, rendezvous operations, orbital altitude & inclination changes, and orbital transfers,– generally, operations demanding high-thrust impulsive maneuvers. In addition, Green...

The low-pressure micro-resistojet: Modelling and optimization for future nano- and pico-satellites

The aerospace industry is recently experiencing growing interest in very small spacecraft like nano- and pico-satellites. However, these very small satellites are still being developed in most cases without a dedicated propulsion system limiting their capabilities. The micro-resistojet has been recognized as a suitable propulsion system for...
